Abstract
1/1 resumo métodos e aparelho para limitar uma mudança de um valor de acionamento num controlador eletropneumático métodos e aparelho de exemplo para limitar uma mudança de um valor de acionamento num controlador eletropneumático são divulgados. um método de exemplo divulgado inclui determinar um limite de deslocamento de um controlador com base em ruído em pelo menos um de um sinal de controle ou um sinal de retorno, calcular um valor de acionamento com base no sinal de controle e no sinal de retorno e mudar o valor de acionamento calculado se uma dif erença entre o valor de acionamento e um valor de acionamento anterior for maior do que o limite de deslocamento do controlador.1/1 Summary Methods and apparatus for limiting a change of a trigger value on an electropneumatic controller Example methods and apparatus for limiting a change of a trigger value on an electropneumatic controller are disclosed. A disclosed example method includes determining a noise-based controller shift limit on at least one of a control signal or a return signal, calculating a trigger value based on the control signal and the return signal, and change the calculated trigger value if a difference between the trigger value and a previous trigger value is greater than the controller travel limit.
